An easy way to check that out: replace the "rol r0" by an "inc r0".
That way r0 will cycle through all 65536 values, and you should easily
see that in the lights.
If that doesn't help, try replacing the reset with a "mov r0,
@#177570" (010037 177570, and of course the branch becomes 000774).
Then the incrementing pattern should show when the Display register is
selected.
